This vertical machining center features a **CAT40 spindle taper** designed for robust, precise tool holding in CNC milling operations, supporting a **vertical spindle orientation** and a 20-tool automatic tool changer (ATC). The machine operates on **3 axes (X, Y, Z)** with travels of **20.5" in X, unspecified in Y, and 14.2" in Z**, all capable of rapid traverse speeds up to **1,890 inches per minute (ipm)**. The CAT40 taper provides a 7/24 taper angle which ensures a secure and rigid connection between the spindle and tooling, minimizing chatter and enhancing machining accuracy. This taper is widely used for its balance of strength and versatility, suitable for various materials and cutting conditions. The spindle taper accommodates tooling with a maximum tool diameter generally up to around 3.15" and features standard CAT40 tooling retention systems common in industrial CNC machining centers. The automatic tool changer with 20 tool capacity allows efficient tool switching and improved productivity in machining cycles. The machine is configured for applications requiring precise vertical milling with high feed rates, supported by a durable spindle interface and a rigid work support table, enabling effective handling of mid-size parts with substantial rigidity during cutting. Its travel ranges and feed rates position it well for complex 3-axis milling operations demanding speed and accuracy with standard CAT40 tooling compatibility common in modern CNC systems.
